Contrary to the other reviews, I find the bra super secure and comfy. I’m a 34C/32D and have M. I’ve used it for hiit workouts, weight training and running. I would only have the strap unbuckled for strength training though. 

I really like this sports bra. I can't really speak too much for support as I have a smaller bust so usually any sports bra will do the trick for me but I do really like the feeling of this one. It's thick and has great coverage, and everything is kept in place! I love the detail on the back that can be worn 2 ways. The only negative I have is that some of the detailing comes off pretty quickly and easily but it's still good quality aside from that

The back is great however not having the straps hooked in racer back style doesn't give much support if larger chested. I am a size 34c and bought a medium. Great fit and comfortable. Still has some bounce but only used for hiit workout so far

Whilst this is an extremely funky and cool little sports bra that looks awesome on the little reflective strips fell off after the first wash (cold wash), which is a shame because it looked fab on the sports bra. The matching leggings are perfect! Overall, it's a gorgeous gym outfit!

Worn for 20 minutes and the reflective studs came off. The design is poor as the studs are placed on the band around the elastic band. They look great, and the fit is good too. Such a shame that this had happened.

Sturdy bra with good enough support. Not happy that the little details have fallen off before even getting a wear out of it. Good for working out. Would probably buy again.
